Home Forums .NET libraries Xceed Zip & Real-Time Zip for .NET I found a zip file that Xceed Zip cannot unzip but that WinZip can. Is this a bug?

    For over 7 years as of this writing, the PKZip v2.0 zip file format has been available and in widespread use. That’s the format Xceed Zip uses to read and write Zip files. The reason Xceed Zip won’t unzip that file is because Xceed Zip is not backwards compatible with old Zip files made with PKZip v1.x. The extra code required in order to unzip these older Zip files is not required by most developers and was intentionally left out in order to provide lighter components.
